I purchased years ago and my wife and I share lists. Finally did away with all the sticky notes and hand written lists. Then, in the last year they updated the app. Now the entire screen goes black when it syncs and it kicks me back to the previous list that I was in 2 or 3 times. I frequently end up adding stuff to the wrong list as a result! Extremely annoying. Plus the time spent syncing is ridiculous, as is the frequency. Went from being one of my favorite apps to one of the most annoying. Please, please, please fix the sync problems, so that I can go back to loving your app.
